I guess director thought it's not relevant, but it would be really nice to know at least if it was just civil war in UK (though strange to call the other side terrorists then and mother had on computer projections for mainland Europe casualties) or it was some European war with organized attackers/Muslims (though rebels didn't seem very Muslim).

I was fast forwarding a bit in beginning, so just to be sure, only the girl was her blood cousin and the boy she fucked, was not her cousin?

why someone killed group of those boys in camp? it seem like they were killed by soldiers who took them and not by rebels, since there were no dead soldiers around, only civilians

It starts like easy going indie movie and then sort of changes into serious drama/thriller (I had pretty big expectations after nice scene with explosion in forrest), but somehow they forgot such details like is she really dying her hair during tough times when she has them even in the end colored at same length?
